Yimalini iKhoyili yeAluminiyam?

Ukufumana ithegi yexabiso elingatshintshiyo ye Ikhoyili yealuminiyam ayifane yenzeke kwimarike yanamhlanje yesinyithi. Ukuguquguquka kwempahla kunye neenkcukacha zokwenziwa ezilungelelanisiweyo zihlala zitshintsha amanani okugqibela. Awukwazi ukukhangela ikhathalogu eqhelekileyo kwaye ukhethe ireyithi ethe tyaba. Abathengi bajongana nomngeni onzima wokufumana yonke imihla. Kufuneka ulungelelanise ngqo iinkcukacha zeprojekthi ngokuchasene nemiqobo engqongqo yohlahlo lwabiwo-mali. Ngeli xesha, kufuneka uphephe imirhumo efihliweyo yolungiselelo kunye nokucwangciswa kwemarkups ezingalindelekanga ezinyakazela kwii-invoyisi zakho. Eli nqaku libonelela ngesakhelo esicacileyo, sesigqibo sokukunceda ukubala ngokuchanekileyo iindleko. Siza kukubonisa ukuba uvayina njani na abathengisi ngokufanelekileyo ngaphambi kokuba ucele ikowuti esemthethweni. Qhubeka ufunda ukuze ukwazi ukubala ngasemva kwamaxabiso ezinto ezikrwada kwaye ukhusele imida yeprojekthi yakho.

Izinto eziphambili zokuThatha

• Amaxabiso ayaguquguquka kwaye asekelwe ikakhulu kwifomula enamacala amabini: ixabiso elisisiseko le-LME (London Metal Exchange) kunye nomrhumo wokuyilwa womthengisi.

• Ixabiso lekhoyili ye-aluminiyam ngetoni nganye iqheleke ngokubanzi ngokusekwe kwibakala lengxubevange (umzekelo, i-1000 series vs. 5000 series grade marine).

• Ubukhulu bekhoyili yeAluminiyam , ububanzi, kunye nonyango olungaphezulu (njengokwaleka kombala okanye i-anodizing) zezona ziguquguqukayo ezinzima kwiindleko zokusetyenzwa.

• Imingcipheko efihliweyo yokuthengwa kwempahla ibandakanya iindleko eziphezulu zokuthumela ii-odolo ezinomthamo ophantsi, ubuncinci be-odolo quantities (MOQs), kunye namazinga ezinto ezilahliweyo ezivela ekunyamezeleni ukwenziwa kwezinto.

Ifomula yoMgangatho weXabiso: Ukulungiswa kweeNdleko

iBaseline Equation

Abathengi bahlala besokola ukuqonda ukucaphula kwesinyithi esintsonkothileyo. Amaxabiso emizi-mveliso axhomekeke kulwakhiwo lwemathematika oluthe ngqo. Unokwahlula iindleko zizonke zibe ziintsika ezintathu eziphambili. I-equation yesiseko ihlala ibonakala ngolu hlobo: Iindleko ezipheleleyo = (i-LME Aluminium Ingot Price) + (Fabrication / Processing Premium) + (Logistics / Tax). Ukuqonda le equation ilula kukukhusela ekuhlawuleni kakhulu. Ikuvumela ukuba ube wedwa kanye apho umboneleli unokufihla iimarkups ezingeyomfuneko.

Ixabiso eliSiseko le-LME (Uguquko)

I-LME (London Metal Exchange) ixabiso elisisiseko lisebenza njengondoqo oguquguqukayo wocaphulo lwakho. Iimarike zorhwebo zehlabathi ziyalela lo mlinganiselo wesiseko yonke imihla. Abarhwebi babala nge-metric toni nganye okanye ngeponti nganye ngokusekelwe kubonelelo lwexesha lokwenyani kunye nemfuno. Ukothuka kweemarike, iingxaki zamandla, kunye nemigaqo-nkqubo yorhwebo lwamazwe ngamazwe itshintsha la manani rhoqo. Ababoneleli abathembekileyo bahlala besebenzisa idatha ye-LME engafihliyo, efakwe isitampu sexesha xa uyila ikowuti yakho. Oku kungafihlwa kwakha ukuthembana okubalulekileyo. Kufuneka usoloko ufuna ukubona umhla wesitampu sexesha se-LME kulo naluphi na uqikelelo olusesikweni.

INtlawulo yaNyanga yokuFamba (umahluli)

Iprimiyamu yokwenziwa isebenza njengowona mahluko uphambili phakathi kwababoneleli abahlukeneyo. Ii-ingots ze-aluminiyam ezikrwada zifuna umsebenzi obalulekileyo womatshini.

UVavanya njani uMboneleli weKhoyili weAluminiyam

Ukukhangela umthombo wakho wesinyithi kufuna inkuthalo engqongqo yokusebenza. Kuya kufuneka ujonge kude ngaphaya kwe-pitch yokuqala yokuthengisa. Sincoma ukuvavanya amaqabane kwiindidi ezine ezibalulekileyo ukuqinisekisa impumelelo yexesha elide.

Ukungafihli kwamaxabiso

Okokuqala, funa ukucaca kwamaxabiso apheleleyo ukusuka kusuku lokuqala. Umntu othembekileyo Umthengisi we-aluminium alloy coil uqhekeza iikowuti zabo ngokupheleleyo. Bahlula ngokucacileyo ixabiso lesiseko se-LME eliguquguqukayo kwiprimiyamu yabo yokwenziwa kwangaphakathi. Bakwabeka bucala iintlawulo zokupakisha kunye nempahla kwikowuti esemthethweni. Ukuba umthengisi wenqaba ukwenza ezi ndleko, yithathele ingqalelo njengeflegi enkulu ebomvu.

Ukunyamezelwa kweZakhono

Okwesibini, kuvavanya amandla abo okunyamezela kwangaphakathi. Khangela ukuba umthengisi unokuqinisekisa unyamezelo oluthile ngokubhaliweyo. Sukuyamkela imigangatho ebanzi, esezantsi yoshishino yeeprojekthi ezibuthathaka. Ukuchaneka kubaluleke kakhulu ngexesha lokwenziwa kokwenziwa rhoqo. Buza imibuzo eneenkcukacha malunga nokuchaneka kwe-edge slitting. Buza malunga nokuqina kwazo zonke ii-master roll.

Supply Chain uzinzo

Okwesithathu, vandlakanya uzinzo lwekhonkco lonikezelo. Phanda amaxesha abo okukhokelela kwimveliso. Buza malunga nomthamo we-buffer ye-inventory yabo yangoku. Kuya kufuneka wazi ukuba basebenza njengendawo yokuvelisa ngokuthe ngqo, iziko lenkonzo yengingqi, okanye nje umthengisi. Abarhwebi bongeza omnye umaleko ongeyomfuneko kwi-invoyisi yakho. Ubudlelwane obuthe ngqo bubonelela ngonxibelelwano olungcono kunye nokusombulula ingxaki ngokukhawuleza.

Uxwebhu olusemgangathweni

Okokugqibela, funa amaxwebhu akumgangatho ongqongqo kuyo yonke into ethunyelwayo. Soloko ujonge iziqinisekiso zokwenziwa kwe-ISO ezihlaziyiweyo. Cela iingxelo zovavanyo lokusila (MTRs) kwiibhetshi zakho ezithile. La maxwebhu asemgangathweni aqinisekisa ukwakheka kweekhemikhali zentsimbi. Baqinisekisa ngokungqongqo isivuno soomatshini kunye neepropathi ezithambileyo ozihlawuleleyo. Ngaphandle kwe-MTR, awukwazi ukuliqinisekisa ibakala.

Ukuqukumbela

Ukukhusela unikezelo lwesinyithi oluthembekileyo kufuna ukucinga ngobuchule kunye nezibalo ezinononophelo. Esona sicaphulo sisezantsi asifane silingane nesona sisombululo sinexabiso lilonke. Iindleko eziphezulu zothutho, isivuno esibi sezinto eziphathekayo, kunye nee-MOQ ezingaguqukiyo zitshabalalisa ukonga okubonwayo ngokukhawuleza. Soloko ubala iindleko ezifike ngokupheleleyo phambi kokuba wenze isigqibo sokuthenga sokugqibela. Beka phambili ababoneleli abanikezela ngamaxabiso apheleleyo elubala kunye nemigangatho yomgangatho ophezulu wemveliso.

Phambi kokuba ufikelele kwikowuti esesikweni, qokelela ezona meko zichanekileyo zokusebenza. Bhala ialloyi yakho efunekayo, imeko yomsindo, ubukhulu bomzimba, kunye nobubanzi obuchanekileyo. Qikelela iitoni zakho zonyaka ezilindelekileyo ukuthethathethana ngezaphulelo zevolumu ezingcono kakhulu. Iimfuno ezicacileyo zobugcisa zisusa ukuqagela kumthengisi kwaye zikhawulezise inkqubo yokucaphula.
